Stansted airport should continue to be regulated because of its dominance among budget and charter airlines, the Civil Aviation Authority has decided, saying the airport's market power was likely to grow between 2014 and 2019 as airport capacity constraints continued to tighten in London.

The CAA sets a cap on what Stansted and the UK's two other regulated airports, Heathrow and Gatwick, can charge for landing fees. The cap will now remain in place until April 2014.
